SPACE CHARGE


Many industrial, medical and scientific products rely on the behaviour of charged particles. Engineers must design systems to precisely control charged particle generation, their manipulation and their interaction with matter and electromagnetic fields. Whatever the application, be it X-ray tubes for NDT or today’s most advanced medical scanners, ion sources for high energy physics research, or sputtering systems for thin film deposition, Opera’s Space Charge module gives designers a versatile, fast and accurate design and optimization capability.

Capabilities

  • Self-consistent, relativistic, space charge analysis
  • Combined electric and magnetic field tracking
  • Includes beam magnetic field, current flow and dielectric charging
  • Multiple surface and volume emission models
  • Primary and secondary emission
  • Plasma modelling
  • Fast and accurate

Applications

  • X-ray tubes
  • Electron and ion beam sources and beam transport systems
  • Magnetic and electric lenses and deflection systems
  • Sputtering and ion beam implantation
  • Electron beam microscopy and lithography
  • Mass spectrometry
  • Field-effect displays

MAGNETS


High performance magnets play an important role in science, medicine and industry. Magnet designs are often made for a relatively low number of installations and re-design of tooling required for manufacture must be minimized. Material costs are also often very high. These characteristics mean that prototyping is both time consuming and expensive. Opera provides the software tools to give confidence that designs are right first time by giving the designer the ability to create virtual prototypes that can be relied on. In most applications, the quality of the magnetic field is the important criterion for an optimized design.

Capabilities

  • Parameterized pre-formed coil shapes.
  • High precision field calculations.
  • Magnetic field can be used to steer and focus a charged particle beam.
  • Charged particle tracking can be performed to determine the beam path through individual magnets or multi-magnet systems.
  • Losses and forces can be automatically transferred to Opera’s multiphysics simulations and their effect on electromagnetic performance can be readily assessed.
  • The effect of the inductance and resistance of the magnet on AC and transient performance can be analysed by coupling the winding to its power supply circuit Superconducting quench can also be modelled.

Applications

  • Particle accelerators
  • Magnetic resonance imaging (MRI)
  • Nuclear magnetic resonance (NMR)
  • Spectroscopy
  • Ion implant systems
  • Proton therapy facilities
  • Magnetic separation
  • Magnetic particle guidance

Other important design considerations include:

  • Losses in AC, ramped and pulsed magnets
  • Inductance
  • Mechanical forces
  • Quench protection circuitry

ELECTRICAL MACHINES


The current demands for high efficiency, reliability and low cost of electrical machines require the use of extremely accurate and integrated simulation tools. Whether designing a motor or a generator, an axial or radial flux topology, rotating or linear motion, Opera provides the right tools for the task. Opera integrated multi-physics capabilities allow for a complete machine characterization using a multi-disciplinary approach. A powerful scripting language allows for rapid prototyping and optimization, while the integrated Machines Environment gives users the possibility to quickly and easily setup their customized machine designs.

Capabilities

  • Motional solvers including mechanical coupling and coupled electrical circuit
  • Power supply control including soft, swtiching, PWM, current and position feedback
  • Modelling of skewed structures within motional solvers
  • Eccentricities and fault operation
  • Demagnetization of permanent magnets
  • Loss calculation including hysteresis effects

Rapid Design

System level modelling

Opera-2d and Opera-3d can be linked directly to industry-standard software to co-simulate the transient performance of the complete drive or electromechanical system. A dedicated Opera ‘block’ can be configured by the user to co-simulate any type of electrical machine or linear motion device as an integral part of an overall system.

Machines Environment

Motor and generator models can be rapidly setup and analyzed using parameterized templates. Standard design calculations can be performed to obtain useful results such as back-EMF, cogging torque, load torque, open and short-circuit curves. Coupled multi-physics analyses that include stress calculations are also available in the Machines Environments allowing for quick analysis of complex problems. A direct coupling with the Opera Optimizer allows the refinement and optimization of designs based on user requirements. Extensive model customization can be included in the 2d and 3d Machines Environments in order to meet the user’s design requirements.
